i looked into the clutch replacement yeah stock clutch wont hold up for the hp, I was told earlyer that chrysler did not put the supercharger on the six speed because it would dog the gear box, well i have come to find out that they actually put the automatic on the supercharge srt6 because they wanted somthing everyone could enjoy( people who cant drive stick), so far theres no proof that the six speed cant handle the power of a turbo ect..... and if u look hard enought like i have been doing you'll find very impressive SLK's running on the same trans we have in the base and limit six speeds one company i know makes a upgrade for the slk clutch for stage one to five, our six speeds can more then handle the 100 or even 200 ex hp, i am a new owner and have a limited crossfire with a six speed not a srt6 and have found more people on this form go from hear say then real situations. http://www.specclutch.com/ i got this web site from Hddp who has been more than helpfull on these forms, he reall knows what hes talking about, but no one has ever put a turbo on the cars so infact you can not guess that the trans will not hold up, its only assumed from chrylser techs, i like the forms but for some reason when u ask a question like hey how can i up grade my clutch you have maybe two people that can respond and the rest are people that start fights or other crap please leave that to other forms maybe in the special sec, of the site, we will find out about the trans in less than a year and a half because like i posted before i will have a sts system for my car built by car view two and xoitice motor sports p.s im young (21) and old guys rock too ! lol
